12 Claims.

My invention relates to computing mechanism, and more particularly to improvements in crossfooting registers of the type disclosed in my Patent No. 1,576,961, dated March 6, 1926.

The principal object of my invention, broadly speaking, is to provide a simplified carry-restoring or resetting mechanism designed with a view to reducing the number of parts heretofore utilized in resetting the type of two-way transfer mechanism with which this particular crossfooter register is equipped, and particularly adapted for easier operation by the usual transfer restoring key.

To the accomplishment of the foregoing, and ancillary objects as will presently appear, there as been illustrated in the accompanying drawings a preferred embodiment of my invention, which will be set forth in detail in the following description and defined in the claims appended hereto.

In the drawings:

Figure 8 is a vertical sectional View, on an enlarged scale, of one of said value wheel units, and

Fig. 9 is a fragmentary view in vertical section taken on the line 6-9 of Fig. 2.

The cross-footer with which my invention is more particularly concerned, is of the type forming part of the equipment of the well-known Elliott-Fisher billing machine of commerce. In this machine, printing mechanism, including number keys, is mounted on a carriage which travels over a subjacent fiat platen to line and letter space the printing point of the machine over the work. As the printing point is advanced through the denominational orders of a column, a master actuator, fast upon an actuator shaft mounted on the carriage, is correspondingly advanced across denominational number wheels of a relatively fixed column register, associated with that particular column, whereby denominational selection in the column register is effected.

Upon operation of the number keys to print, the master actuator is operated through suitable well known difierential mechanism, in degree corresponding to the value of the key operated, to accumulate in the column register the values printed.

The cross-footer mechanism, proper, is mounted on one end of the beforementioned carriage, as shown in my Patent No. 1,576,961, between side plates 1 and 2, respectively, connected together by tie-rods 3 and forming part of the cross-footer casing.

Included in the cross-footer mechanism is a series of toothed denominational cross-footer number wheels 4 rotatable on a shaft 5 suitably journaled at its ends in the side members 6 and 1 of a frame forming an internal part of the cross-footer structure.

A toothed cross-footer actuator, or wheel, 8, (Fig. 2) is splined upon a squared cross-footer shaft 9 for driving connection with the beforementioned master actuator shaft Ill, and for denominational selection and operation of the wheels 4, as follows:

The master actuator shaft I ll has fast thereon a gear I l no-rrrially in driving connection with the cross-footer shaft 9 through a shiftable gear l2 constantly in mesh with said gear II and also meshing with a gear l3 fast on the cross-footer shaft 9. In the normal relation of the gears, the number wheels 4 are driven in a direction to effect addition in the cross-footer. l2 interposes a normally idle twin gear M in the train to drive the number wheels 4 in the reverse direction and effect subtraction in the crossfooter. For a more detailed disclosure of the above drive and control mechanism therefor, at- 1 tention is invited to my patent No. 1,455,196.

The cross-footer actuator 8 is advanced laterally across the number wheels 4 for denominational selection thereof, by actuator advancing mechanism, the principal elements of which are an actuator advancing shaft !5, provided with oppositely extending fixed arms [6 and [1, respectively, and rotated during travel of the carriage,

by engagement of the shaft arm IS with relatively stationary devices, (not shown) to advance an actuator carriage l8 along a guide bar l9 through the medium of the shaft arm H. A fork projecting from the actuator carriage embraces the grooved hub of the cross footer actuator 8, to shift Shifting the gear show, and reference may also be made to Foothorap Patents 1,775,223; 1,839,211, and 1,847,429 which are likewise directed to carrying mechanisms for registering devices, but throughout this series of improvements, substantially the same carry-restoring mechanism was retained, typified by the provision of a pair of opposed carry-resetting bails, and a positive unyielding connection between the bails and their operating mechanism.

It became desirable to improve the carry-restoring mechanism, in order to materially relieve the resistance to operation present in the former restoring mechanisms; to simplify and reduce the number of'parts and their arrangement, and to enable the provision of a stronger, quicker carry.

To these and other ends, a single resetting bail is substituted for the two bails which heretofore had been required to directly contact with opposite sides of the carrying elements, such single resetting bail being arranged to act upon the several toggle driving levers, to which the toggles are pivotally connected, instead of embracing the toggle levers, as heretofore.

Herein lies one difference between this invention and the prior Foothorap patents, in that the toggle levers of the present invention are not straightened or brought to their normal cocked positions by the pressure of opposed bails applied to opposite sides of the toggles, but instead, are drawn into their straightened or cocked positions by pressure applied longitudinally of the toggle.

It was found after this simplification, that the previous positive connection between the carryresetting bail and its operating lever, as shown in Foothorap, 1,455,196, for instance, was unsatisfactory for the following reason.

To enforce the complete restoration of the carrying mechanism to normal, cocked position, a full stroke device is provided, which prevents the return to normal of the operating lever for the carry-restoring bail until the operating lever had been given its full effective stroke.

The operating lever is afforded a stroke sufiicient in length to insure the return of the carrying pawls to their normal cocked positions, and in order to avoid the necessity for close workmanship and slight clearances, the length of stroke of the operating lever is increased beyond that found sufficient to reset the carrying pawls, such additional travel of the operating lever being provided to enable the release of the full stroke mechanism, which, as is obvious, must occur subsequently to the complete restoration of the carrying pawls.

Because of the former positive connection between the operating lever and the carry-restoring bail, the latter was driven, not only through so much of its stroke as was necessary to fully reset or cook the carry-resetting pawls, but also through the additional and final portion of the stroke during which the full stroke device was released.

Naturally, the restoring bail, during such final portion of the stroke of the operating lever, shifted the carrying pawls past their normal cocked positions, and stored excess energy in the carry-operating springs. The operating lever, upon its release, was then returned to its normal position by the usual spring, aided by the excessive energy stored in vall the carrying springs, and the carrying mechanism itself was likewise returned smartly from its excessively retracted position to its cocked position.

Such overthrow return of the carrying mechanism from its extreme retracted position to its cocked position, was not particularly troublesome in the former type of carrying mechanism, wherein the spring tensions were carefully balanced, lighter springs being used, and the carrying pawls being guided during their return from such excess limit of movement to their cocked positions so that their ends contacted with the stop bars 63, 63a, (Foothorap 1,455,196) Fig. 1, but upon combining the simplified carry-resetting mechanism of the present application with the improved carrying mechanism, shown in Foothorap, 1,576,961, for instance, wherein the retention of the carrying mechanism in cocked position depends upon the maintenanceof the carrying toggle in dead-center position, the fixed shaft 2! on which the carrying heads 20 are pivoted, preventing excess restoring travel of the toggle-like carrying mechanism, it was necessary to vary the former arrangment.

To enable the use of the full stroke device with the carry-resetting device, so as to insure the return of the tripped carrying mechanisms to their normal cocked positions, and then by a farther travel of the operating means for the carry-resetting mechanism, effect the release of the fullstroke pawl, without displacing the reset carrying mechanisms, I arrange to first restore the tripped carrying members to their normal cocked positions during the major portion of the travel of the operating lever, and thereafter, the operating lever is, in effect, disengaged from the carry resetting bail, and continues its travel to release the full stroke device, without affecting the carrying mechanism.

That is to say, the operating lever completes the latter portion of its effective stroke without imparting an excessive retraction to the carrying mechanisms, which are not retracted farther than is safely necessary to recock them properly.

Thereafter, the operating lever and its carry-restoring bail return to normal, while the carrying mechanisms remain in their cocked positions.

This arrangement permits the use of much stronger springs for affecting the carrying operation in a much more satisfactory and snappier manner.

Coming now to the various features of my invention, a series of individual driving levers 22 is associated with the carrying heads 20. In this instance, and as distinguished from the construction of my former Patent No. 1,576,961 the driving levers 22 are of bell-crank form, pivoted or fulcrumed at 15, below the associated heads in a slotted guide block 23 to provide, in their normal position, substantially horizontal and vertical arms 24 and 25, respectively, the horizontal arm 24 being preferably longer than the vertical one for a purpose presently seen.

Individual motor springs 26, having their opposite ends connected to a fixed bar 21 and to the vertical arms 25 of the driving levers 22, urge the horizontal arms 24 of said levers upwardly, that is, toward the axis of the heads 20. Each associated carrying head 20 and its driving lever 22 is connected by a link 28 pivoted at its upper end to the head 20 below the axis thereof at 29. In termediate its ends, said link is pivoted at 30 to the horizontal arm 24 at .a point intermediate the free end of said arm and the fulcrum point 15 thereof, and substantially equidistant from the latter as compared with the point of connection of the motor spring 26. Normally the pivot points 29 and 3B are aligned with the axis 2| of the head 25, in dead center relation to form a toggle lock resisting the urge of the spring 26, in which relation the parts are retained by a notched detent lever 33 tensioned by a spring 34 to engage .a roller 35 on the lower free end 3| of the link 28. In this type of transfer mechanism, a carrying operation is initiated by a widened tooth (not shown) on the number wheel 4 engaging a trip member 36 of the sub-jacent head 20 and moving the same from its dead center position in one direction or the other, as the case may be, to break the toggle-locked relation of the parts. Thereupon the appropriate motor spring 25 becomes effective to continue the movement of the head 20, which, through the medium of a pair of combined carrying fingers and locking dogs 37 mounted thereon picks up and rotates the number wheel 4 of next highest denominational order as fully set forth in my aforesaid Patent No. 1,576,961. The devices designated 38 are the usual overthrow preventing and wheel centering devices which need merely be identified in passing.

It is to be noted that the operating levers 22 always move in the same direction, i. e., clockwise as viewed in Fig. 4, to continue movement of the heads 20 in either direction. It follows that by movement of said levers 22 in a single opposite direction said heads may be restored to normal position after movement in either direction.

Returning now to the cross-footer number wheels, and with particular reference to the value wheels 4| and the before-mentioned drive, each cross-footer number wheel 4 forms part of a number wheel unit, including a relatively thin driving gear 39 of smaller diameter to permit close spacing of said wheels and for clearance of the gear by the laterally movable actuator 9.

Mounted in the cross-footer, on a shaft 40, (Fig. 6) and parallel with the number Wheel units, is a series of value indicating units, including value wheels 4|, corresponding in size and denominaticnal order to that of the number wheels 4, and peripherally space-d forwardly of the latter to bring them nearer to the eye of the operator. Preferably, the value wheels 4| are formed of very light white material, and provided with peripheral value designations to 9 of a color, for instance, black, sharply contrasting to their white background so that the numerals are presented to the eye in a striking manner.

Number and value wheels 4 and 4 I, respectively, of corresponding denominational order are connected by a gear drive, including the before-mentioned driving gear 39, a driven gear 42- afiixed to one side of the value wheel, and an idler gear 43 interposed between two adjacent value wheels 4|.

In order that a given number of value wheels of a maximum peripheral width may be used in a given space with such an interposed idler, the value wheels 4% are provided with chambered side. faces 44, (Figs. 7 and 8) respectively, whereby adjacent value wheels partially house the driven gear 42 and thus permit close spacing of said wheels. A hub portion 45 on one side of the gear 42 projects through an axial bore 46 in its value wheel 4| and slightly into the chamber 44 at the opposite side of the value Wheel to provide a relatively small end thrust bearing for the adjacent driven gear 42.

The driven gear 42 is riveted to its value wheel, the heads of the rivets 4'! being countersunk in slots 48 (see Fig. 4) formed in one side face of said value wheel 4| and radiating from the bore. The idler gear 43 is of disc-like form, being preferably stamped out, or otherwise constructed, from thin sheet metal, of the requisite rigidity, whereby it is accommodated with the proper degree of clearance between the closely spaced value wheels 4| Coming now to the transfer restoring mechanism, a vertically rocking transfer restoring bail 49 is mounted on the before mentioned slotted guide block 23 and includes a pair of laterally spaced bail levers Q pivoted at 75 coaxially with the driving levers 22. The bail levers 50 are substantially co-extensive in length with the horizontal arms 24 of the driving levers 22, and are connected at their free ends by a bail rod 5| overlying the free ends 32 of said arms 24.

Normally the transfer restoring bail 49 occupies an elevated position over the free ends 32 of the driving levers 22, determined by cooperating stops on the bail levers 55 and guide block 23, respectively, in the present instance having the form of angularly disposed stop arms 52 on the bail levers and a stop face 52' on said block engaged by the stop arms.

The transfer restoring bail 49 is depressed from I its normal elevated position by bail rocking or operating mechanism, as follows: Rearwardly extending, intermediate levers 53 fixed at their forward ends upon a bail-operating rock shaft 54 journaled in and projecting through the side members 6 and 'l, are connected at their inner ends by links 55 with the bail rod 5|. The intermediate levers 53 are preferably shorter than the bail levers 58 for a purpose presently explained.

The bail operating shaft 54 is rocked in a direction to depress the bail 49 by means of the usual transfer restoring key 56 (Figs. 1 and 2) and lever 57, the latter pivoted at 53 (Fig. 4) to a suitable part of the cross-footer frame, and depressible against the tension of a spring 59 having its opposite ends suitably connected to the key lever and cross-footer frame respectively. Associated with the key lever 51 is full stroke mechanism substantially the same as that disclosed in my U. S. Patent No. 1,455,196. described, a full stroke rack 60 is fixed on the register side plate I for engagement by a full stroke pawl 6| pivoted on the key lever 51 and having an engaging arm 6| a adapted to contact with one end of the rack 6|], a releasing arm 6|b for coaction with a fixed stop 62, and a tooth 6|c with which a detent dog 63 pivoted on said lever 51 coacts under the urge of a suitably arranged spring 63a to retain the pawl in either an engaging or releasing position. Normally, as shown in the drawings, the engaging arm 6|a contacts the rack 60 to position the pawl 6| for engagement with the rack during the down stroke of the key lever 51 so that said lever is prevented from returning. When said lever approaches the limit of its down stroke the releasing arm 6 b engages the fixed stop 62 and rocks the pawl 6| to releasing position in which it is freed from the rack 60 and the key lever 51 released for return.

The key lever 51 is operatively connected to the shaft 54 by a crank arm 64 (Figs. 3 and 5) fast on the shaft and a cross-head 65 (Figs. 3 and 4) pivoted to said crank arm and key lever by studs 66 and 61 respectively. The connection between the shaft 54 and key lever 51 is a yielding one, a slot 69 being formed in the cross-head 65 providing for play of the stud 91 thereon whereby the key lever 57 is permitted a limited degree of downward independent movement against the tension of a retractile spring 69, the latter suitably connected to the stud 61 and a pin 70 on said cross-head.

In machines of the class herein illustrated, it is customary to enforce a carry-resetting operation after the entry of an amount into the cross totalizer 4|, by means forming no part of this invention, which operates to lock the machine until the carry-restoring lever 51 is actuated.

Pressure on the lever 57 rocks the lever downwardly about its pivot 52. The stud 61 on the lever normally lies in the upper'end of the slot 68 in the pivoted cross head 65, in which position it is held by the strong spring 39.

Therefore, the stud 61, as it descends with its carry-restoring lever 51, carries with it the cross head 65, the compensating spring 59 at this time serving as an unyielding link between the carryrestoring lever and the cross head.

By reason of the pivotal connection 66 between the cross head and the arm 54 fast on the rock shaft 54, clockwise motion is imparted to the rock shaft and the intermediate arms 53 fixed thereto and connected by the short links 55 to the carry-restoring bail or member 49, to swing the member 49 counter-clockwise and press the bail rod 5| against the forwardly projecting extensions 32 of the drive levers 22.

Tripping of any of the carrying devices 29, 28 and the consequent flexing or breaking of the corresponding toggle-like carrying device, releases the spring 26 connected with the corresponding drive lever 22 torock the drive lever clockwise and turn the wheel 4 of next higher order in one direction or the other depending upon whether the totalizer is conditioned for addition or subtraction.

The flexed condition of the tripped carrying device enables the extension 32 of the driving lever 22 to approach the restoring bail rod 5| quite closely so that as the restoring bail rod starts on its counterclockwise travel, it soon picks up or collides with the extensions 32 of the driving levers 22 associated with the tripped carrying devices, and rocks the driving levers counterclockwise back to their normal positions, retensioning their springs 26. i

The cross head spring 89 is superior to the combined strength of the driving springs 26 to prevent relative movement between the carry-restoring lever 5'! and the carry-restoring bail 49 during the return of the driving levers 22 counter-clockwise to their normal cocked positions.

The pressure applied by the carry-restoring bail rod 5| to the extensions 32 of the driving levers 22 is transmitted thereby to the flexed toggle-like carrying devices in a direction longitudinally of the links 20, 28 constituting the carrying devices, and serves to straighten the toggle-like carrying devices by lengthwise draught thereon, instead of by lateral pressure against opposite sides thereof, as heretofore.

It will also be noted that the restoring of the carrying devices to their cooked or equilibrated positions, is positively effected by direct action of the carry-restoring member 49 on the carrying devices, applied through the driving levers 22.

As the toggle lever carrying device straightens under the continued pressure of the carry-resetting bail, the roll on the lower free end 3| of the flexed link 28 rides over one or the other of the high points flanking the seat in the outer forward end of the detent 33, rocking the detent slightly against the tension of its spring 34, and as the toggle lever finally straightens into its dead center position, the roll 35 settles into the seat of the detent, aided by the spring 34.

Due to the arc of travel of the lower free end of the link 28, the roll reaches its seat without necessitating a very substantial displacement of the detent 33 for locking the carrying device in cocked position.

The opposition presented by the detent springs 34 as the roll 35 wipes over the high point flanking the seat in the detent, added to the increasing opposition presented by the springs 26 of the driving levers 22, as the latter are returned to their normal positions, tends to overcome the compensating link 69.

As the carry-restoring effective stroke to re-cock the toggle-like carrying devices 20, 28, it draws the full stroke pawl 5| over the ratchet E50, and at the time that the carry-restoring devices 29, 28 are completely restored, the carry-restoring lever 5'7 is still locked against return, by the full-stroke mechanism.

It, therefore, becomes necessary to release the full stroke mechanism, to which end, the carryrestoring lever 5'! is permitted an excess travel beyond that necessary to re-cock the carrying devices.

But, as heretofore explained, due to the balanced or equilibrated condition of the carrying devices when in their reset positions, it is undesirable to disturb them in their reset conditions nor can the carrying devices be drawn farther downwardly, through continued action of the restoring bail 49, thereon, heretofore incident to the farther travel of the restoring lever, due to the fact that the carrying heads 29 are mounted on the fixed shaft 2|.

I, therefore, have arranged that the carryrestoring lever 51, shall complete its effective stroke by movement relatively to the carry-resetting bail 49, 5| and the carrying devices, subsequently to the complete restoration of the latter, without disturbing the delicate balance of the cooked carrying devices.

To this end, I have interposed the cross head spring ,or compensating link 69 between the carry-restoring lever and the carry-restoring bail 49.

Therefore, as the carry-restoring lever 51 con tinues on its effective stroke after the carrying devices 29, 28 have been reset, to release the full stroke device, the pressure on the lever 51 will be transmitted, as before explained, by the stud 61 to the strong cross head spring or compensating link 69, to the cross head 65, and through the pivot stud 66, arm 64, rock shaft 54, intermediate arms 53 and links 55, to the carry-restoring ball 49, the rod 5| of which at this time, lies in contact with all of the extensions 32 of the reset carry-driving levers 22 which now occupy the positions shown in Figure 4.

The fully tensioned driving springs 26 of the entire set of driving levers 22 oppose farther rocking of the driving levers in counter-clockwise direction, added to which is the resistance opposed by the springs 34 of the entire set of locklever 51 rocks on its ing detents 33, and farther counter-clockwise travel of the combined driving and restoring levers 22 is impossible, as the toggle carrying devices are in line with their fixed shaft 2!.

The combined resistance thus opposed to the farther travel of the restoring bail 49 is superior to the strength of the compensating link or cross head spring 69, which, therefore, yields and enables the carry-restoring lever 57 to complete its effective stroke, alone, the stud 67 traversing the slot 6:3 of the cross head 65, and tensioning the compensating spring 6% The slot 68 is of sufficient length to enable the carry-restoring lever 57 to complete its stroke without farther depression of the cross head 65 which may, however, swing slightly on its pivot stud 66 to prevent any binding of the stud 67 in the slot 68 due to the eccentric travel of stud 67 relatively to the stud 66.

The extra travel afforded the carry-restoring lever 51 subsequently to the complete resetting of the carrying devices 20, 28, enables the carryrestoring lever to effect the disengagement of the full stroke pawl 6| from the full stroke rack 60, as explained heretofore, the full stroke pawl detent 83 operating to latch the pawl Bl out of engagement with its rack.

The carry-restoring lever 51 is now released to the action of its return spring 59, aided by the tensioned compensating link 69 which snap the restoring lever upwardly, the stud 8? of the lever retracing its path in the slot 68, until it contacts the upper end of the slot, the cross head 65, is arm 64, the rock shaft 54, with its intermediate arms 53, and the restoring bail 49 being all returned to their normal idle positions.

The carry-restoring lever may be arrested in its home position in any suitable manner, that shown being the provision of the curved tails 52 on the rear ends of the arms 50 of the carry-restoring bail which collide with the face 52 at the rear of the guide block 23, as heretofore explained.

It will be noted, particularly, that the cross rod 5| of the restoring bail recedes from the extensions 32 of the driving levers 22, upon the return of the parts to normal, without affecting the set carrying devices and without having forced them past their set positions during the extra travel afforded the carry-restoring lever 51 to disengage the full-stroke mechanism.

It will also be noted that the single restoring bail 49 operating to impart a longitudinal draught on the toggle-like carrying devices 20, 28, resets the latter irrespective of the direction in which they were flexed in effecting an additive or subtractive carry.

The yielding compensating link 69 serves as a cushion between the carry-restoring lever 57 and the carry restoring bail 49, and the operation of the restoring key is eased by distributing the load thereon, and relieving the restoring lever of the extra duty of overcoming the carry driving springs 26 and detent springs 34, heretofore imposed where a positive connection existed between the carry-restoring lever and the carry-restoring bail.

The foregoing transfer restoring mechanism proper is particularly designed for operation by a very light stroke on the restoring key for the following reasons.

First, the transfer restoring bail 49 exerts a greater leverage against the operating lever 22 than that exerted in opposition thereto by the spring 26 and inertia of the head 20, because of the fact that the bail rod 51 engages the operating lever 22 at a point farther from the pivot point of the latter than the points of connection of the spring 26 and link 28 to said lever. Second, an increase in leverage is effected between the key 58 and the bail 49 by virtue of the fact that the intermediate arms 53 are shorter than the lever arms 5% of the bail lever 49 to which they are connected. Obviously therefore a greater degree of pressure will be exerted by the levers 53 against the bail 49 than that imposed upon the key 56.

The foregoing constitutes a detailed description of a preferred embodiment of my invention, but it is to be understood that right is herein reserved to such changes and modifications as fall fairly within the scope of the protection prayed.

In a register, the combination with transfer devices, and individual driving levers connected thereto, and operable in one direction to effect the transfers, and in the opposite direction to restore the transfer devices; and a transfer-restoring lever; of a transfer-restoring bail operable upon the driving levers to actuate the latter in transferrestoring direction; and bail-rocking mechanism interposed between the transfer-restoring lever, and the bail, including a compensating connection adapted to constitute a substantially rigid link during the resetting of the tripped transfer devices, and further adapted to yield subsequently to the resetting of the transfer devices to aiford the transfer-restoring lever an additional travel relatively to the transfer-restoring bail.

11. In a register, the combination with rocking carrying devices operable in either of two opposite directions; individual driving levers therefor; and means to trip the carrying devices; of carry-restoring mechanism, including a resetting member having a constant path of travel and operable to reset the carrying devices irrespective of the direction in which they rocked when tripped; means to limit the resetting stroke of the resetting member; an operating element connected to the resetting element for movement relatively thereto; and a yielding compensating link to prevent relative movement between the operating element and the carrying-resetting member until the arrest of the carry-resetting member at the limit of its resetting stroke.

12. In a register, the combination with carrying devices; and driving means therefor; of a carry-resetting member limited in its resetting travel; an operating element for the resetting element; a rocking link connected with the carryresetting member; a loose connection between the operating element and the link; and a yielding connection between the link and the operating element to provide for concomitant movement of the operating element and the carry-resetting member until the latter reaches the limit of its resetting travel.
